Abstract

A light-source optical system according to the present invention includes a laser light source that radiates excitation light; a wavelength conversion unit that is irradiated with the excitation light to generate light having a wavelength different from that of the excitation light; and a light deflection and convergence unit that causes an odd number of light beams greater than or equal to three, radiated from the wavelength conversion unit in mutually different directions, to converge at and re-enter the wavelength conversion unit from the backward direction of another light beam, radiated in a direction different from the directions of the odd number of light beams greater than or equal to three, thereby making the odd number of light beams greater than or equal to three overlap the other light beam.
